United States Patent 3,492,772 STRUCTURAL ASSEMBLY Frank C. Bergman,Chicago, Ill., assignor to Garey Corporation, a corporation of IllinoisFiled Apr. 5, 1967, Ser. No. 628,655 Int. Cl. E04b 1/24; E04c 3/04; A471/10 US. Cl. 52-633 5 Claims ABSTRACT OF THE DISCLOSURE The structuralassembly for supporting display panels, or the like, comprises aplurality of rigid frame members mounted on bottom support members andend frames hinged to the outermost bottom support members. Spring clipshold the upper portions of the frame members in side by siderelationship, and retaining members welded to the bottom support membershold the lower portions of the frame members together. A reinforcingmember is interposed between two adjacent frame members to increase theload bearing capacity of the assembly in any selected area.

This invention relates to a structural assembly adapted to support anddisplay garments that are mounted on clothes hangers, or merchandise ofany kind that may be held on a shelf. The assembly may also hold panelscarrying advertising or promotional material to accentuate the salesappeal of the merchandise. The invention is particularly concerned withmeans for securing and holding a plurality of frame members in side byside relationship to form an assembly, and means for reinforcing theassembly whereever desired, so that it may be of any desired length.

In assemblies of the type with which this invention is concerned, it hasbeen common practice to fabricate the assembly in individual units andto complete the assembly at the installation site by means of amultiplicity of nuts and bolts, or other fastening members equallytroublesome to handle.

In accordance with the present invention, the rigid frame members areassembled into a rigid structure without using nuts and bolts, or anysimilar fastening members. A novel connector clip is positioned in oneend of the top stretcher of one of the frame members to be assembledwith other similar frame members. The bottom stretcher of each framemember is provided with a slot near each end, and a bottom supportmember is provided with a retaining member having two upstanding prongs.The bottom stretchers of two adjacent frame members are impaled on theprongs of one retaining member and then the top stretcher of the framemembers about each other. The connector clip located within one of thetop stretchers is moved longitudinally into the top stretcher of theadjacent frame member and interengages same to affix and maintain thetwo top stretchers against relative longitudinal and transversalmovement.

FIGURE 15 is a cross-sectional view, taken in the plane indicated by theline 15-15 of FIGURE 14.

Referring to the drawings, the structural assembly comprises a pluralityof rigid frame members 11 supported on bottom support members 12 and 13,a pair of end frames 14 hinged to the outermost bottom support members(only one of which is shown) and a reinforcing member 15 interposedbetween adjacent frame members in any area in which it is desired toincrease the load bearing capacity of the assembly.

Each of the frame members comprises a top :stretcher 16, a bottomstretcher 17, and a pair of vertical posts 18 interconnecting the topand bottom stretchers. The top stretcher is tubular, and its bottom wall19 defines a relatively narrow slot 21 extending longitudinallythroughout its length. Equidistant from each end of the top stretcher,the slot 21 is widened to provide an elongated opening 22 having a pairof shoulders 23 on opposite sides of the slot 21 at its end adjacent theend of the stretcher, the function of which will be referred tohereinafter.

The bottom stretcher 17 is preferably in the form of an inverted channelmember defining a pair of transverse slots 24 extending through its topwall 25. Each slot 24 is spaced from the adjacent end of the bottomstretcher a distance slightly greater than the distance between the endof the top stretcher and the end of the opening 22 remote therefrom.This spatial relationship between the slot 24 and the adjacent end ofthe bottom stretcher enables the vertical posts 18 to be located closeto the ends of the top and bottom stretchers without hampering theinterconnecting of the adjoining ends of adjacent top stretchers.

Each vertical post 18 is aligned vertically with one of the slots 24 andis welded to the top wall 25 of the bottom stretcher while in saidvertical alignment. The opposite end of the posts is welded to thebottom wall 19 of the top stretcher to form a rigid frame member 11. Thepost 18 is tubular, and its front wall 26 defines a series of uniformlyspaced vertically disposed slots 27. The back wall of the post 18 isalso provided with a series of slots 27 A plurality of brackets (notshown) may be mounted on each post with one end of each bracketprojecting into one of the slots 27 The brackets are adapted to supporthang rods, from which garment hangers can be suspended, or shelves, onwhich miscellaneous merchandise may be supported. The front and backwall of each post 18 also defines a pair of vertically spaced indents 28below the lowermost slot 27 for a purpose hereinafter disclosed.

A panel retainer strip 29 is snapped over each bottom stretcher toprovide bottom support for a display panel 30. Each strip 29 has alength equal to the distance between the vertical posts 18 of the framemember 11. Suitable panel clips 30 are snapped on each post 18 toprovide support for the vertical edges of a display panel 30. The upperedge of the display panel extends into the slot 21.

A retaining member 31 is rigidly secured to each bottom support memberfor preventing relative lateral movement between the lower portions ofadjacent frame members. Each Ibottom support member 12 comprises atubular bar 32 and legs 33 depending from its outer end. The retainingmember 31 comprises a plate 34, having upstanding ears 35 strucktherefrom, and a strip 36. The plate 34 is welded to the top surface ofthe bar 32. Each ear 35 is spaced the same distance from the end of theplate 34 adjacent thereto. The strip 36, bent to provide upstandingprongs 37 projecting from its opposite ends, is welded to the bottomsurface of the bar 32, and its prongs 37 are welded to the outer ends ofthe plate 34. Each prong 37 has a length greater than the distancebetween the upper indent 28 and the bottom of the post 18. The upper endof each prong 37 is rounded, as indicated at 38, to facilitate entryinto the slot 24.

Adjacent frame members 11 are secured together by aligning a tubularpost 18 of one of the frame members with one of the prongs 37 and movingthe frame member downwardly until its bottom stretcher engages the plate34. The prong 37 has a thickness just enough less than the width of theslot 24 to provide a minimum clearance as it passes therethrough. Thewidth of the prong 37 is sufficient to allow it to fit snugly betweenthe indents 28 projecting from opposite walls of the tubular post 18.When the bottom stretcher rests on the plate 34, one car 35 projectsinto the channel of the bottom stretcher to provide additional rigidityfor the connection between the frame member 11 and the bottom supportmember 12. The adjacent frame member has one end impaled on the otherprong 37 to secure the lower portions of the frame members together,with the ends of the adjoining bottom stretchers in abutting end to endrelationship. The ends of the adjoining top stretchers are also inabutting end to end relationship.

The outer ends of the two outermost frame members are secured to bottomsupporting members 13 in the same manner as the opposite ends of theintermediate frame members are secured to the members 12. The onlydifference relevant to the mounting of the frame members is that theplates 38 and 39 are shorter than the plates 34 and 36, and each supportmember 13 has only a single prong 37.

It is not feasible to duplicate the connecting structure of the bottomstretchers at the top of the assembly for several reasons. The top ofthe assembly is often visible, and a duplication of the bottomconnecting structure at the top would detract from the neat appearanceessential to an attractive assembly. An additional disadvantage of suchstructure is that the assembly would lack vertical stability. The framemembers could be separated from the assembly merely by lifting themupwardly.

In accordance with the present invention, the top stretchers of adjacentframe members are secured together, without nuts and bolts, by a novelconnector clip 41. The clip is inserted into the open end of the topstretcher of one frame member, and is locked into engagement with theopen end of the adjacent frame member merely by moving the cliplongitudinally into the top stretcher of the adjacent frame member.

Each clip 41 comprises a channel 42 and a spring 43 seated in thechannel. The channel, with the spring 43 seated therein, is adapted tofit within the tubular top stretcher 16. The channel 42 comprises a flatbottom wall 44 and two reversely bent sidewalls 45 extending upwardlyfrom the longitudinal edges of the wall 44. The bottom "wall 44 definestwo openings 46 and 47 that are adapted to register with the openings 22near the abutting ends of the two top stretchers with which the clip isinterengaged.

The spring 43 comprises a fiat strip 48 adapted to be juxtaposed againstthe bottom wall 44 of the channel 42 and having resilient fingers 49 and51 extending upwardly from bend lines 52 and 53, respectively, atopposite ends of the strip 48. The outer end portion of each of thefingers 49 and S1 is curved downwardly, as indicated at 54 and 55,respectively, to prevent the ends of the fingers from digging into theinner surface of the top wall of the stretcher 16. Two ears 56 are bentdownwardly from opposite longitudinal edges of the strip 48 near thebend line 52 and project through the opening 46. Two similar ears 57 arebent downwardly from the strip 48 near the bend line 53 and projectthrough the opening 47. The spring 43 may be riveted to the bottom wall44 of the channel 42.

The overall height of the spring 43, i.e., the vertical distance betweenthe lowermost portion of the ears and the uppermost portion of theresilient fingers, is greater than the inside height of the topstretcher. Accordingly, in order to insert one end of the clip into theopen end of the top stretcher, the spring is compressed by pushing oneend of the strip 48 upwardly, by a screw driver 59, or some similartool, while the finger 49 is held by engagement with the top wall of thetop stretcher. When the cars 56 are moved upwardly to clear the bottomwall 19 of the top stretcher, longitudinal pressure is applied to theclip to move it inwardly of the stretcher, with the resilient springfinger 49 bearing against the inner surface of the top wall. The ears 56are beveled at their entering end, as indicated at 61, to facilitateentry of the clip into the top stretcher.

When the clip is pushed into the top stretcher far enough to cause theopening 46 to register with the opening 22, the ears 56 snap downwardlyinto the opening 22 to lock the clip against accidental removal from thetop stretcher. Any attempt to pull the clip out of the top stretchercauses the ears 56 to engage the shoulders 23, and the strip 48 must bepushed upwardly to allow the ears 56 to clear the shoulders 23 beforethe clip can be removed. After the cars 56 have snapped into the opening22, the longitudinal pressure against the outer end of the clips iscontinued and the outer end of the strip is pushed upwardly to allow theclip to be moved inwardly of the top stretcher with the cars 57 inengagement with the top surface of the bottom wall 19. The clip ispushed inwardly until its outer end is flush with the outer end of thetop stretcher. The clip cannot be pushed into the top stretcher farenough for the ears 57 to engage the opening 22 in which the ears 56 areengaged because the longitudinal spacing between the ears 56 and 57 isgreater than the length of the opening 22.

One edge of the opening 46 defines a notch 63, and the opposite edge ofthe opening 47 defines a notch 64, to facilitate longitudinal movementof the clip 41 when the top stretchers are in abutting relationship. Theslot 21 permits the end of the screw driver 59 to be engaged with thenotch 63 or 64. Pressure against the notch 63 moves the clip 41 in onedirection, and pressure against the notch 64 moves it in the oppositedirection. When two top stretchers abut each other, the clip 41,positioned entirely within one of the stretchers with its ears 56projecting into its opening 22, can be moved longitudinally to positionone end of the clip in the adjacent top stretcher with its ears 57engaging its opening 22. Each of the cars 56 and 57 engages the outeredge of its opening 22 to hold both top stretchers against relativelongitudinal movement.

Each outermost bottom support member has an end frame 14 securedthereto. The two end frames are duplicates and, therefore, only one ofthem is shown and described. The end frame 14 comprises two slotteduprights 65 welded to a top stretcher 66 and a bottom stretcher 67. Thebottom stretcher 67 has two hinge hooks 68 welded thereto. The hingehooks are shaped so that they can be inserted in slots 69 providedtherefor in the bottom edge of the horizontal bar 71, as shown in FIGURE5.

The top stretcher of the end frame is detachably secured to the topstretcher of the adjacent frame member 11 by a connector clip 72. Theclip 72 comprises a channel 91 and a spring 92 seated in the channel.The channel 91 comprises a flat bottom wall 93 and two reversely bentside walls 94 extending upwardly from the longitudinal edges of the wall93. The wall 93 has a longitudinal slot 95 extending from one endadjacent each side wall 94, and its opposite end projects beyond theends of the side walls to provide a tongue 96 adapted to fit in anopening 97 in the top stretcher 66. The wall 93 has an embossment 98adapted to fit tightly in the opening 97 to hold the channel 91 firmlyin place until the channel is welded to the top stretcher 66 to fix itpermanently in place. The wall 93 also has an opening 99 extendingacross its entire width, and a narrower opening 101 closer to theslotted end of the wall.

The spring 92 comprises a flat strip 102 having transversely extendingwings 103 at one end adapted to enter the slots 95 and bent upwardlyslightly to fit within the inverted V-shaped spaces of the side walls94. The opposite end of the strip 102 is bent to form a resilient finger104. The inner end of the finger 104 is bent downwardly, as indicated at105, to facilitate engagement of the spring and the open end of thetubular top stretcher 16 into which the channel '91, with the spring 92has seated therein, is adapted to fit. The strip 102 has two cars 106depending from its opposite longitudinal edges and a resilient lip 107closer to the wings 103. When the spring 92 is seated in the channel 91,the ears 106 extend through the opening 99 and the lip 107 engages theopening 101. When the top stretcher 16 is pushed into engagement withclip 72, the legs 106 are moved downwardly into engagement with theopening 22 in the bottom wall of the top stretcher by the resilience ofthe finger 104. The top of the end frame is thus interlocked with thetop stretcher of the adjacent frame member and cannot be separated untilthe bottom wall of the spring 92 is pushed upwardly to disengage thelegs 106 from the opening 99 and the lip 107 is clear of the edge of theopening 101.

The structural assembly hereinabove described may be made of any desiredlength, but it is sometimes desirable to reinforce the structure byinterposing a reinforcing member 1 5 between any two adjacent framemembers to increase the load bearing capacity of the assembly in one ormore specific areas. The reinforcing member comprises a pair of tubularposts 73 and 74 welded at their lower ends to the tubular bar 32 of abase support 12 and converging upwardly in the vertical plane of saidtubular bar. The upper ends of the posts 73 and 74 terminate in spacedrelationship below the plane of the top stretchers, and areinterconnected by clip means 75.

The clip means 75 comprises a bottom channel 76 having its open topcovered by a top channel 77 welded thereto. The sideewalls 78 of thebottom channel 76 each defines an opening 79 large enough for aU-bracket 81 to pass through. The bracket 81 comprises a fiat bar 82having its ends bent upwardly, as indicated at 83, and its longitudinaledges recessed, as indicated at 84. The openings 79 have a restrictedportion 85 extending downwardly to the top surface of the bottom wall 86of the channel 76. The recesses 84 permit the bar 82 to rest on thebottom wall 86. The inter-engagement of the recesses 84 and theshoulders defining the restricted portion of the openings 79 to preventrelative movement between the bracket 81 and the bottom channel 76,except in a direction normal to the bottom wall 86.

Relative movement between the bracket 81 and the bottom channel 76 isprevented by the top channel 77 which comprises a top wall 87 and twodepending sidewalls 88. The sidewalls 88 straddle the sidewalls 78 ofthe bottom channel and have aligned notches 89 in their lower edges tofit over the fiat bar 82. The top and bottom channels 77 and 76 areWelded together after they have been assembled with the bracket 81, andthe clip means 75 is handled as a unit in the assembly of the entirestructure. The outer ends of the bottom channel 76 fit into the spacedupper ends of the posts 73 and 74, with the bracket 81 extendingparallel to the top stretchers. The clip means 75 may be welded to theposts 73 and 74 to provide an integral reinforcing member 15 that can behandled as a unit when it is positioned between two frame members 11.

When the reinforcing member 15 is interposed between two frame members,a retaining member 31' holds the bottom portions of two adjacent framemembers 11 against relative lateral movement. The retainer 31' on thereinforcing member is a duplicate of the retainer 31 except that thedistance between the prongs 37 is longer, to compensate for thethickness of the legs 73, 74 of the reinforcing member 15 that isinterposed between the adjacent ends of the top stretchers 16. Theoutermost portions of the bottom wall 19 of two adjacent top stretchersrest on the fiat bar 82, and the upwardly bent ends 83 of the bracket 81extend upwardly into the opening 22, in the bottom Walls 19 to hold thetop stretchers against relative longitudinal movement.

The method of assembling the frame members into a unitary assembly canbest be understood by referring to FIGURE 2 of the drawings. The firststep in the assembly is to insert one of the clips 41 in one open end ofeach top stretcher 16. The clip is pushed into the top stretcher farenough to allow the ears 56 to snap into the opening 22 so that itcannot be removed except by pushing the spring upwardly to move the ears56 upwardly above the plane of the shoulders 23. The opening 22 in thebottom wall of the top stretcher is long enough to permit the clip 41 tomove inwardly of the top stretcher until the outer end of the clip isflush with the end of the top stretcher. It will be understood that eachof the frames is positioned for assembly with the clip 41 locatedcompletely within the right hand end of the top stretcher and flushtherewith, as viewed in FIGURE 2.

The left hand end portion of the bottom stretcher 17 is then impaled onthe prong 37 projecting from the support member 13. The right hand endportion of the stretcher 17 is then impaled on the prong 37 projectingfrom the support member 12. The left hand end portion of the stretcher17 of a second frame member is then impaled on the other prong 37 of thesupport member 12 and the adjacent open end of the top stretcher of thesecond frame member is moved into abutting horizontal relationship withthe right hand end of the first frame member. The clip 41 is then pushedto the right into the adjacent top stretcher, without moving the ears 56out of the opening 22, until the ears 57 snap into the opening 22 of thetop strecther of the second frame member. This process is repeated untilthe unit is completed. A reinforcing member may be inserted if the loaddemand reqllllfiS same.

In the places where the assembly is reinforced, the method of assemblingthe bottoms of two frame members is the same as previously described,except that the prongs 37 of the retaining member 31' are spaced apartslightly more than the prongs of the members 31 to allow for thethickness of the clip 75 which is used in place of the clip 41. The clip75 has ears 83 adapted to project into the openings 22 adjacent theadjoining ends of the top stretchers on opposite sides of thereinforcing member 15.

Each end frame member is positioned with its hinge lugs 68 in the slot69 of the support member 13, and is then swung pivotally upwardly andits clip 72 is pressed into the adjacent open end of the top stretcher16. Ears 106 depending from the outer end portion of the clip 72 snapinto the opening 22 of the top stretcher and interlocks the end framemember and the adjacent frame member 11.

When the assembly, or any portion thereof, is to be dismantled, a screwdriver or similar tool is pushed up in the slot 21 so as to engage theunderside of the spring of the clip. The spring is then pushed upwardlytill the ears 56 or 57 clear the adjacent shoulder 23, and the clip isthen pushed longitudinally to remove either ears 56 or 57 from theopening 22. The length of the opening 22 permits this longitudinalmovement of the clip. When one end of the top stretcher of any framemember is disengaged from its clip 41, the frame member may be lifted atthat end to disengage its bottom stretcher from the prong 37 on which itwas impaled.

The dismantling of any portion of the assembly enables the assembly tobe remodeled readily by inserting diiferent frame members or reinforcingmembers wherever desired.

Although a preferred embodiment of the invention has been described inconsiderable detail, it will be understood that the description thereofis intended to be illustrative, rather than restrictive, as many detailsof construction may be modified or changed without departing from thespirit or scope of the invention. Accordingly, it is not desired to berestricted to the exact structure described.
